Welcome to IIS Torr
Saturn is a great target, I still go for it each session if it is up. As Mike has said it is quite a long way north for us so we are looking through lots of atmosphere so the views this "season" have been not so good but that only makes the good times more special. The Cassini Division is a challenge this year as the angle of the rings is closing, I usually only manage to see it at the ends of the rings if that makes sense this year. Last year it was no problem to see it all round.
As for the cold, wet scope I just cap mine and bring it inside. When it is warm I open the ends to allow any moisture inside to escape and when it is dry cap it again. Eyepieces are treated the same, I lay them out on the table and next morning cap them and put them away.
Cheers
